Energy Efficiency

Energy Auditing

An inefficient compressed air system can quickly become the most expensive piece of equipment in your plant. We use ELITEpro™ Recording Poly-Phase Power Meters by Dent Instruments to analyze your compressed air systems and electric motors.

After properly monitoring your compressed air system we can confidently recommend energy efficient air compressors and accessories, and qualify you for a PG&E energy rebate. On average, we are able to save our customers 30% or more in energy savings alone.

7 Ways to Reduce Your Energy Costs

  1. Repair air leaks. The American Council for an Energy Efficient Economy has published reports which states that 15% of the energy used to generate compressed air is lost in leaks. Other estimates range from 15% to 25% and higher.
  2. Reduce the operating pressure. Most system operate at a pressure much higher than required to operate the air equipment. When the compressor produces 100PSI air, and the demand remains constant, every 2PSI of pressure increase will also increase its energy consumption by approximately 1 percent.
  3. Replace undersized air piping to reduce pressure lost.
  4. Consider heat recovery. During operation, compressors generate a large amount of heat which can be used for other purposes in the plant. A well designed heat recovery system can recover over 50 percent of the compression heat energy. The waste heat has many applications including process use, space heating, and preheating boiler feedwater. A 50 horsepower air compressor rejects approximately 126,000 Btu per Hour.
  5. Pipe in outside air for the compressors. Most mechanical rooms are hot. Cooler air increases the efficient of the air compressor.
  6. Use sequencing controls for multiple compressor installations. Rotary screw compressors operate most efficient at full load. When operating more than one air compressor, sequencing control system should be added to optimize the operation of the air compressors. Savings of 10 to 20% and over can be obtained by installing the sequencing controls.
  7. Use energy-efficient motors. When purchasing a new air compressor specify the motor to be energy efficient or consider purchasing an air compressor with variable speed drives that are now on the market.
